FLYINGACHINE.

Application filed April 12,

To /n't fir/loin 'it may concern lle it linoivn that l, Mann (ioLniN, residing at Brooklyn, in the county ot Kings and Stato. of New .ivorl, have invented neiv and useful Improvements in Flying-Ma` chinos, ol' which the following is aY specilisation.

This .invention relates to new and useful improvements in flying machines, and pertains more particularly to saitety appliances therefor,

The I )rimary object of the invention 1s to provide a safety device for aeroplanes which is in the form or' a parachute.

further object of the invention is to provide a parachute oi sullicient dimensions as to be capable of operation to serve to check the descentof an aeroplane in case ot accident thereto While in flight.

A further object ol' the invention 'is to so construct a parachute as to rende-r the same capable of being folded in such a manner as to otter no interference to the successful operation ol' the machine in Hight.

il further object ot the invention is to provide means tor effecting an operation of the planes simultaneously With the operation ol the parachute.

Referringto the drawings:

Figure l is a side vievv of a conventional type ol aeroplane7 showing the parachute l-'olded in its inoperative position.

l? il is a similar view showing the parachute extended.

Fig. B is a detail vieiv ot one ot' the planes.

Fig. #t is a detail view of the operating mechanism for the planes.

llig. is a detail vievv of a portion of one of the rib members showing' parts in section.

Referring more particularly to the draw-r Specification of Letters Patent.

1919. Serial No. 289,566.

ends ot said sliding` ribs is secured the peripheral edge 16, of the body 17, of the parachute, the central portion 18 ofthe parachute 1T being secured to the fuselage at the metal band 13. i

lli/haunted in suitable bearings 19 in the fuselage l() is a shaft 20, and secured t and adapted to be rotated by said shaft 20 is a plurality ot pulleys or drums 2l. The shaft 2O is rotated by means of a spoked hand whecl, and is held in position by means of the dog` 253 ivhich 'engages the gear Wheel 24C. A

The number of pulleys 21 is determined by the number of ribs 15 and leading- :trom an eye it formed on each rib 15 to its respective pulley is a ,small Wire 27. These Wires 27 are adapted to be Wound around their respective pulleys to maintain the parachute in its folded position when not in use.

The planes ll and l2 are each provided on their forward edge with a hinged section 30 which is adapted to be moved to elevate the machine, and these hinged sec- .tions are operated by means of a lever 31 which is positioned in the fuselage adjacent the drivers seat. From this construction it will be seen that the center of gravity ot' the machine can be changed or shifted when the machine occupies a dangerous position where the operator cannot right the same. `Whenthns shifted the center of gravity is in line with the longitudinal axis ot the fuselage which causes the parachute to open promptly as will be understood.

This lever 31 is connected to a shaft 32 which extends longitudinally or' the planes ll and 12, and is connected by means ot the bell crank levers 33 to the links or rods 3ft which in turn are connected at their opposite ends to the hinged sections 30 or the planes. By this construction it Will be seen that the two hinged sections oit the planes 11 and 12 are operated simultaneously` ln operation, if through accident, the ma- A chine should start a rapid descent, the lever 5l is operated to rock the shaft 332 and elevate the forward hinged sections of the aeroplane to cause the machine to elevate and prevent what is commonly termed nose diving.

is this operation is completed, the link 35 serves to release the dog or pavvl 23 and permit ot the unwinding of the spools 21 thus allowing the parachute to unfold to retard the descent of the machine and cause the same to reach the ground without any undue shock or strain.

In a modified form of the invention the upper and lower planes are each provided with a hinged section which in turn is controlled by means of a link operated by the same lever which serves to operate the forward hingen sections of the planes. By this construction, it will be seen that when the forward hinged sections are operated to ca use the machine to elevate, the rear hinged sections are likewise operated to release the free ends of the ribs of the parachute and release the same to operative position.

Having thus described the invention what is claimed is:

l. ln an aeroplane, a fuselage, a parachute secured to the tail end of the fuselage, means for normally holding the parachute closed against the fuselage, means for releasing the parachute to permit the same to open, planes carried by the fuselage and provided with hinged sections, and means for operating said sections concurrently to shift the position of the center of pressure with relation to the longitudinal axis of the fuselage prior to operating the parachute releasing means.

2. In an aeroplane, a fuselage, a parachute secured to the tail end of the fuselage, means for normally holding the parachute closed, means for releasing the parachute to permit the same to open, planes carried by the fuselage and provided with hinged sections, and means for operating said sections concurrently to shift the center of pressure of the machine in line with the longitudinal axis of the fuselage prior to operating the parachute. releasing means.

ln testimony whereof l have affixed my signature.
